Using a Pic on the Server

Hey folks,

I'm upgrading my database, and I'd like it to do something simple, like have a client session access a picture file on my Linux server's Pics directory.  However, I'm stumped. 

I can use the @ServerListDirectory("/home/manager/Desktop/Sesame/Pics") and see the .png file I want to access, but when I try to have my splash page have a picture field = the full string (ie.:

SplashLogo = "/home/manager/Desktop/Sesame/Pics/SplashLogo.png"

It won't call my server's data.  Is there a better way to do this?

Thanks!

Okay ... slightly better question. I've uploaded the splash logo to our website ... so how can I tell the splash screen to access the .png file located on the web?

Thanks!

Not sure if you can get an image from the web to work as the splash image directly. I believe you need to put a local copy on each workstation (or have it on the server, and accessible via a mapped drive or a UNC path).

Hmmm ... mapping the server is problematic, as we have some remote/WAN network users.

Can anyone think of some @shell coding that would pull the .png image from the internet to a local file directory?

If using @Shell (or any of the other commands like that), you can use wget or Curl to download the image.

You might also be able to get @HTTPGet to download an image file, though you would need to decode it from base64 to binary.

OK!  I managed to work out an option for resolution ... it won't work on Linux clients, but it's probably unlikely.

Here's what I wrote ...

Code
Select All
if FileExists("C:\sesame2\pics\KDCLogo.png")
{
	KDCLogo = ".\Pics\KDCLogo.png"
}
Else
{
	p = @chr(34) + "powershell -command " + @chr(34) + "& { (New-Object Net.WebClient).DownloadFile('http://kingstondc.com/wp-content/uploads/2015/09/KDCScreenLogo-226x300.png', 'c:\sesame2\pics\KDCLogo.png') }" + @chr(34)
	n = @Shell(p)
	KDCLogo = ".\Pics\KDCLogo.png"
}
